System featuresl Save and recall up to 10 instrument states in non-volatile memoryl GPIB (IEEE-488), LAN, and USB remote programming interfaces are built inl Front panel menu setup for GPIB and LAN parametersl LXI Core 2011 compliant, including a built-in Web serverl SCPI (Standard Commands for Programmable Instruments) compatibilityl Master-Slave function allows for composite output control and display from one unitRegenerative OperationRegenerative operation is automatic and requires no programming on the part of the user. Wheneverthe RPS is sinking current, either by rapidly downprogramming the output, or by discharging an energysource such as a battery, the unit will direct the excess power back to the AC mains. You cannotdisable the regenerative operation.During regenerative operation, the power factor of 0.99 is maintained. Sinewave current distortion isless than 2% at full load. This ensures the quality of the AC signal that is returned to the AC mains.When an AC mains dropout is sensed, galvanic relays disconnect the AC mains and the unit shutsdown. To safeguard your device under test, the RPS provides “anti-islanding” that senses that the gridis live before regenerating power back to the grid.Refer to Common Characteristics for additional information about unit shutdown and restart.Front Panel at a Glance1.
